these questions cannot be answered without real code examples in
addition to the error and stack trace you've given, you are referring
to some token "image" that isn't imported when called upon, most
likely within a relationship() construct, something like:
relationship("image.Image", primaryjoin="image.Image.x == somecls.y")
and that can't be found. You need to ensure that the names referred
to in your string are available to those expressions when
configure_mappers() is called.
as far as py2k/py3k, py3k does a lot of things differently but it's
hard to say what is different here without any tangible examples.
